•208-pin thin quad flat pack (LQFP)††

•256 mini-ball grid array (mBGA)

•32-way set-associative caches

— 16 Kbyte instruction cache

— 8 Kbyte write-back data cache

•32-entry memory-management units

— Maps 4 Kbyte, 8 Kbyte, or 1 Mbyte

•Write buffer

— 8-entry, between 1 and 16 bytes each

•Read buffer

— 4-entry, 1, 4, or 8 words

•Memory bus

— Interfaces to ROM, Flash, SRAM,

and DRAM

— Supports two PCMCIA sockets

† Power dissipation, particularly in idle mode, is strongly dependent on the details of the system design.

†† Package nomenclature has been modified due to industry standardization of packages. LQFP is 1.4mm

thick, thin quad flat pack. Please note that no modification has been made to the package itself.
